About 7.3 milion people were watching Sunday as Austrian skydiver Felix Baumgartner reattempted and nailed the Red Bull Stratos extreme skyjump, freefalling more than 128,000 feet to Earth at 1,342.8 kilometers per hour. He broke the sound barrier but no bones, and garnered congratulatory tweets from NASA and fellow daredevil Richard Branson, and an amusing tribute from Nestle's KitKat. (Update: YouTube reported more than 8 million concurrent livestreams, smashing all previous records, resulting in about 12.6 million viewers including Discovery Channel.)

"After flying to an altitude of 39,045 meters (128,100 feet) in a helium-filled balloon, Felix Baumgartner completed a record breaking jump for the ages from the edge of space, exactly 65 years after Chuck Yeager first broke the sound barrier flying in an experimental rocket-powered airplane. Felix reached a maximum of speed of 1,342.8 km/h (833mph) through the near vacuum of the stratosphere before being slowed by the atmosphere later during his 4:20 minute long freefall. The 43-year-old Austrian skydiving expert also broke two other world records (highest freefall, highest manned balloon flight), leaving the one for the longest freefall to project mentor Col. Joe Kittinger."
